2. Application Worksite Checklist

Engineered with corrosion-resistant brass body and sealed thermistor core to withstand harsh engine compartment conditions:

• Engine Thermal Control: Provides accurate coolant temperature signal to ECU for fuel adjustment and cooling fan activation.
• Heavy Earthmoving & Quarry Operations: Brass housing resists coolant corrosion, dust and vibration under continuous heavy-load operation.
• Long-Hour Mining & Loading Work: Stable temperature reading prevents engine overheating and overfueling fault codes during multi-shift operation.
• Cold Start Control: Reliable temperature signal helps ECU enrich fuel for smooth cold startup.

3. Water Temperature Sensor Troubleshooting & Diagnostic Guide

If your XCMG excavator is exhibiting sensor-related failure, consult the diagnostic guide below:

• Fault 1: Gauge Shows No Temperature Reading
  Root Cause: Failed or intermittent water temperature sensor — ECU receives no coolant temperature signal.
  Solution: Replace with a new water temperature sensor and inspect wiring harness and connector pins.
• Fault 2: Engine Overheating Warning & High Fuel Consumption
  Root Cause: Incorrect temperature signal makes ECU misjudge engine cooling status.
  Solution: Install a new water temperature sensor and bleed air from the cooling system.
• Fault 3: ECU Fault Code P0115 / P0116
  Root Cause: Open circuit, short circuit or corroded sensor connector.
  Solution: Replace water temperature sensor and clean connector terminals; clear DTC with diagnostic scanner.
• Fault 4: Poor Cold Start & Rough Idle
  Root Cause: Wrong low-temperature signal causes incorrect fuel quantity during cold cranking.
  Solution: Replace the water temperature sensor before pursuing expensive fuel system repairs.
• Fault 5: Coolant Leakage at Sensor Thread
  Root Cause: Damaged thread or failed sealing washer on sensor.
  Solution: Replace sensor with new sealing washer; apply proper thread sealant during installation.

5. Frequently Asked Questions & Technical Support

Q1: How do I verify if this water temperature sensor fits my XCMG excavator?
A: Check your original sensor thread size and connector type, confirm your machine is XCMG excavator. Send machine serial number to us for quick fitment check.

Q2: What is the working principle of this water temperature sensor?
A: This is a thermistor coolant temperature sensor. Its internal resistance changes with coolant temperature, converting temperature changes into electrical signals for the engine ECU.

Q3: What should I note during sensor installation?
A: Use a new sealing washer, apply suitable thread sealant, do not over-tighten the brass thread. Refill coolant and bleed air after installation.

Q4: Does this water temperature sensor come with the sealing washer?
A: Yes, each sensor comes with matched sealing washer, ready for direct installation on the engine coolant port.
